Rocket Lab successfully launched its latest HASTE mission—codenamed “Van”—from Launch Complex 2 at the Mid-Atlantic Regional Spaceport in Wallops Island, Virginia. The mission lifted off on Tuesday, November 18, 2025, at approximately 8:00 a.m. EST following a weather delay the previous day.
The mission was originally slated to fly on Monday, but the first launch attempt was scrubbed due to high winds at the launch site. Wallops frequently experiences strong coastal wind layers that can exceed allowable limits for Electron’s lightweight carbon-composite structure. With conditions improving the following morning, Rocket Lab proceeded with a clean, on-time launch on Tuesday, demonstrating both operational discipline and the adaptability needed for high-tempo hypersonic test campaigns.
Electron and the Evolution into HASTE
HASTE—Hypersonic Accelerator Suborbital Test Electron—is built upon the same core architecture as Rocket Lab’s orbital Electron rocket. Electron’s innovations, including its carbon-composite airframe, electric-pump-fed Rutherford engines, and extensive use of 3D-printed components, serve as the backbone of this dedicated sub-orbital test platform.
While Electron’s typical missions send small satellites to orbit, HASTE is engineered for high-energy sub-orbital trajectories. The vehicle supports:
Payloads up to roughly 700 kg
Deployment above ~80 km altitude
Velocity profiles ranging from lower hypersonic speeds into near-orbital re-entry conditions
This positions HASTE between traditional sounding rockets and orbital launchers—offering higher speeds and greater flight realism than sounding rockets, at a significantly lower cost and turnaround time than orbital missions.
The “Van” Mission Flight Profile
The Van mission followed a custom sub-orbital flight path designed to expose its payload to the thermal, aerodynamic, and dynamic environments characteristic of hypersonic flight.
Key elements of a typical HASTE mission profile include:
A high-thrust ascent driven by Electron’s first and second stages
A tailored upper-stage burn shaping the ballistic arc
Payload release at the targeted altitude and velocity corridor
Data collection throughout ascent, separation, and the payload’s hypersonic flight
This architecture allows test teams to gather real-world data on materials, sensors, thermal-protection solutions, and communications links in extreme conditions.
Payload and Mission Objectives
The payload for the Van mission was developed for the Missile Defense Agency (MDA) in partnership with the Defense Innovation Unit (DIU) and Johns Hopkins University Applied Physics Laboratory (APL).
While detailed specifications remain undisclosed, the mission aligns with DIU’s HyCAT (Hypersonic and High-Cadence Airborne Testing) program. Likely objectives included:
Testing hypersonic vehicle components or materials
Evaluating advanced sensors and tracking systems
Collecting re-entry and heating data
Validating guidance or communication technologies at high Mach numbers
HASTE’s capability to deliver payloads into realistic high-energy environments quickly and repeatedly makes it an essential asset for accelerating hypersonic development cycles.
Importance of the Mission
Rocket Lab’s successful execution of the Van mission highlights several broader trends in aerospace:
Commercial hypersonic access is becoming a critical national capability
Responsive launch operations—demonstrated by the 24-hour turnaround after weather delays—are now expected
Cost-effective, repeatable testing is reshaping how hypersonic technologies move from concept to field-ready systems
Small-launch providers like Rocket Lab are increasingly integrated into national security infrastructure
As hypersonic systems take center stage in global defense priorities, rapid test platforms like HASTE are enabling faster, more iterative progress than ever before.
